Beit known that .Lines A. BURKE, residing et Chicago, in the county ofCook and State of Illinois, and a. citizen of the United 5 States, haveinvented o.- new and useful Iniprovenient in )rinters7 Blocks, of Whiehthe following is e i'uli description, reference being .hed to the noooinpnnying drawings, in Which-v Figure l is e pien view showing onesizeof io block ready ior use; Fig. 2, e plsu View showing e block.inoreased in dimensions and ready for use, with the parts broken ont toshow the holding-pins; Fig. 3, an end elevation, with the end section ofthe bloei; removed; Figs. i, I5 5, 6, and 7, plan views showing theinterposed pieces by whioh the width of the block is increased; Figs.8,9, end l0, pien views showing dii'erent-sized end sections forincreased size of blocks.

This invention hos for its objeets to furnish o. biooliior the receptionof stereotype or other printing or embossing plates inode op in sets, sothat the smaller plate will have e. hice-k adopted to receive it, whichhloel een be increased in size transversely and longitndinaliy, to adeptit for the reception of pistes of different sizes, up to the largest;and its nature consists in the several ports und combinotions o1" portshereinafter deserihed, and pointed ont in the elaiins es new.

In the drawings, A represents one section of the sinnilersized bloeit,having et one end a niet-oi facing, fit, with a. earch or hook, z",henenth Whieh the edge of the piste con be slipped land heid, and havingon one oi' its sides d metal facing, m, with an interposed strip, m,between the facing and the block., of o iess thickness than the block,so as to leave a. groove, fm.

0 B is another section of the bloei: corresponding to the section A, endhaving et one end e nietai Peeing, j, with a hook, j', for the edge ofthe plete to pass onder, end having on one side e metal i'zieing, it,with e hook, 7i', to receive the edge of the plate, the sections A B, esshown, being of n corresponding width and length. As shown, the inneredge of the block B is provided with pins b, end the inner edge of thebioek Ais provided with holes af, to reo eeve the pins b and lool; thetwo biochs A B together at their adjoining edges, and the edge of A isalso provided with hoies a,in iine with the holesa. (ShowninFigl.)Theendfneeof each block A B, which receives the end see tion of theooinpiete block, is provided with holes o and a?, es shown in Fig. 3.

C is the end section for completing e bloei: ofthe smaller size, asshown in Fig. l. One side of this bleek is provided with e nietnifacing, Z, and e. hook, l', oorresponding to the feeing end hook of thesection B, and the other side is provided with n inet-:i1 facing, m.,and an interposed strip, in, corresponding to the facing and strip oi'the section A and arranged to iezive e groove to coincide With thegroove m of the section A. The side of the section C which forms the endof the ooinpiete block is provided with e facing, @mend on interposedstrip, m', to leave o. groove, m, so that the conipiete block will haveone side and one end similar in construction, and the side of theseotion C- whieh, When the bloei; is together, lies adjacent to the endoi' A B is provided with pins e, to enter the holes a in the sections AB and attach the end section to the see-tions A B, to forni o block fora. small-sized piste, as shown in Fig. l.

D D D i):j represent interposing strips to be inserted between thesections A B, to forni the Width required for blocks of larger size, Dforming the width for the iirst size next to the smaller, and so on, thestrips inereosing in width up to any desired width of bioek. The strip Dis provided with pins d, to enter the holes a of the section A, end withhoies d', to receive the pins b of the section B and connect thesections and the strip together, and the strips D' D D3 dreeech providedwith pins d, its shown, which pins enter hoies to connect ee-eh stripwith its preceding one, the 9o pins cof the strip D' entering the holesd' of the strip D, end the pins d of the strip D entering the holes inwhich the pins t," of the strip D are inserted, sind the pins d of thestrip D3 entering the holes of the pins d of the 95 strip D, and so on.

E is the end section for the block shown of the next size to thesinniler. This piece Ein length is eqnei to the Width of the sections AB rend interposed strip D, and, as shown in 1Go Fig. 2, between it andthe sections A B is an interposed strip, E', the section E having pins eon its edge, to enter holes e in the strip E', and the strip E havingpins e", to enter the holes c3, so that the three sections A B E will helocked together to form the complete block, and the block can beincreased in length by adding other strips between the section Eand thesections A B, such strips having pins and holes corresponding to thepins e and holes e'.

Frepresents an end section for a block larger than that having the endsection E, and, as

shown, this block has interposing strips G G',

to make the length of the block proportionate to the width, and a longerblock can be produced of the saine width by adding other strips similarto G G', or the block can be foreshortened in length by removing one ormore of the interposed strips. The strip G, as

shown, is provided with pins f, to enter they holes a ot' the sections AB, and such strips are provided with pins and holes to attach one to theother, the strip G having holes to receive pins on the section F.

H represents an end section for a block larger in size than that formedby the end section F.

I I i represent interposing strips formaking the length ot' the blockforined by the end section H and sections A B proportionate to the Widthand length ot' the plate to be secured. The strip l is provided withpins g, to enter the holes in the end ofthe section A B, and the stripsIand I and section H are each provided with pins and holes to interlockthe parts together in the nianner already described for the otherblocks.

J is the end section for a block of a larger size than that formed bythe end section H.

K K KK3 represent interposing strips between the end section J andsections A B, for making the length of block to receive the plate.

L L represent openings in the end sections E, F, H, and J to receive theclamping-blocks. lhe end section C is provided with the opening L only,as only one clamping block and clamp is required for a block ofthe sizeshown in Fig. l, in. addition to the clamp carried by the section A.

IWI .represents the blocks carrying the clamp, one being used for thesnialler-sized plate and two for the other sizes shown, the blocks beinglocated in the holes LL, provided therefor in the end sections of therespective blocks.

N is a sleeve having a screw-threaded hole, and provided with ajaw orflange, n.

O is a screw passing through the sleeve or slide N, and having itshearings at one end in the end of the block M, and located with thesleeve or slide N in a slot or opening in the block IWI, so that byturning the screw the sleeve or slide can be advanced or receded tocanse the iiange or jaw n to bite or clamp the plate onto the block. Aslide andiscrew are also provided for the section A of the block,

and to complete the blocks of larger size two screws are provided, whichscrews are interchangeable with the blocks by inserting the blocks M'which carry thein in the holes L L in the respective blocks E, F, H,and J.

The blocks E F H J are each provided with a facing, Z, and a lip orcatch, Z, under which the edgeof the plate can be inserted, and the endsot' these blocks are provided with a groove, m",'forxned by afacing-strip, in., and an interposed piece, m', above the plane of whichpiece in the toothed wheel o projects, so that by nieans of a rack-facedpiece the wheel can be turned to advance or recede the clamp N.

The pinsffor the strip G of the end section F are at the proper distanceapart to enter the holes a3 of the sections A B, the saine as pinse ofthe end section E, and Vthe saine is true of the pins g and 7i of theend sections H J, and the interposed strips for these end sections F, H,and J have the pins at one side of the pinsfg h, and so arranged thatthe pins of the respective strips will enter the holes in which the pinsare inserted of the adjacent strip in the forni ot' construction shown,and this uniformity in locating the pins is for the purpose offacilitating the putting of the` strips together, as any strip can beplaced in any order desired without particular selection.

In use the sinall-sized block is formed by placing the sections A Btogether, the pins b entering the holes a, and then adding the endsection C. the pins c entering the holes a, the clamps M of the sectionA and the screw O being withdrawn to allow the plate to he inserted whenthese clamps are advanced to hold the plate beneath thelips n of theclamps and the lips 'ij k l ot' the sections A. B C. The block foranothersize plate is produced by inserting the strip D between thesections A B and then adding the end section E, with the interposedstrip E', or niore strips, it a longer block is required, and for thissized block two clamps, N, are provided for the section E, each carriedby a block, M, the blocks being inserted in the holes L L therefor, andthe plate is dropped into position and held beneath the lips n ot' theclainps N and the lips 'ij k Z ofthe sections A B E. The next block insize is produced by adding the strip D to the strip D, between thesectionsA B. and then adding the end section F, with the strips G G, alonger block being i'ornied by adding more strips; and the block iscompleted by taking the blocks M for the section E and placing thein inthe holesL L of the section F, so that a plate can be dropped inposition and be held by the lips a of the clamps N and the lips t" j k Zof the sections A B F. The block for the next size is produced by addingthe strip D to the strips D D', between the sections A B, and thenadding the section H, withthe strips I I l, the block being made longerby increasing the nuniber of strips between the sections A B and sectionH, and being completed by tak- I OO IOj

IIO

ing the blocks M and inserting them in the holes L L' of the section H,so that the plate can be dropped in position and clamped by the lips vn.ot' the clamps N and the lips fij It' Z of the sections A B H. The blockfor the next sized plate is produced by adding the strip D to the stripsD D D between the sections A B and then adding ythe section J, with theinterposed strips K K E, and then inserting the blocks lli in theopenings L L to clamp the plate in position beneath the lips n ol' theclamps N and the lips t" j k Z ofthe sections A B J. The blocks forplates of still larger size can be produced by adding more stripsbetween the sections A B and forming an end section correspondingly forthe required Width produced by the added strips, the end section havingholes and interposed strips and receiving the clamp-blocks M, as beforedescribed.

It is to be understood that the length of block of the various sizes canbe increased or decreased, except as to the smaller block, by adding orremoving the interposed strips hetWeen the sections A B and the endsection; and it will thus be seen that by the use of the sections A B,and the interposing strips therefor, with end sections eorresponding` tothe Width ofthe sections ABand the stri ps, blocks to receive plates ofdifferent sizes can be readily and quickly produced, as all that isnecessary to be done is to add between the sections A B the nnmber ofinterposing strips required for the width of plate, and then add the endsection with interposing strips for the length ofplate; and it will alsobe seen that two blocks, M, carrying clamps N, are all that arenecessary to go with each set, although any nurnber of blocks M may beprovided, it' so desired.

The intel-posing strips to widen the sections A B are each provided witha facing to correspond with the lacing t' j of the sections A B, and theinterposing strips between the sections A B and the end sections forblocks of larger size nre provided each on one end With a facing-stripto correspond with the facingst-rips Z, and on the other end with facingstrips to correspond with the facing-strips m m', to leave a groove, m.

What I claim as new, and desire to secure by Letters Patent, is"

l.' The combination, with two parallel sections, one the counterpart ofthe other, except that one is provided with a sliding catch, of an endsection having a sliding catch, and interposing strips, for producingreceiving blocks for dilt'erent sizes of plates, substan tiallyT asdescribed.

2. The combination, with the two parallel sections A B and strips placedbetween said sections, of an end section, strips placed between saidparallel and end sections, and blocks M, carrying clamps for enablingblocks for plates of dl'erent sizes to be formed and the plates held onsaid blocks, substantially as described.

3. The combination, With the section A, having edge openings a c a a3,and the section B, having pins b b', ot' strips placed betweensaidsections and having corresponding pins and openings, an end sectionhaving pins on one edge, and a strip placed between said end section andthe sections A B and providedwith corresponding pins and openings,substantially as described.

4. The combination ot the parallel sections A B, one of which isprovided with a sliding catch, an end section arranged transversel atone end ot said parallel section and provided with a sliding catch, andstrips placed between said parallel sections and between the paralleland end sections, said strips and sections being connected by pins andopenings l'or receiving the same, and the several sections being provided with clamping-lips, substantially as de scribed.
